The new season has started! The first episode of season 2 seemed a bit all over the place to me, but I'm digging the casting for Melisandre and Stannis & Davos seemed good for what little we saw of them. I think the problem is that there are too many locations and plotlines at this point. In the beginning of GoT all the Starks and Lannisters are at Winterfell and Dany is across the sea, so we can introduce new plotlines all together. Now all the new characters were at Dragonstone, but there were new plots to prepare for the season in King's Landing, Beyond the Wall, Across the sea too.
I'm hoping as the season moves along, they diverge even a bit further from the books and focus on one or two plotlines per episode with just a touch or two on the others, keeping more of the shuffling episode-to-episode rather than scene-to-scene. The 5 seconds of Arya we saw in Ep. 1 indicates they might go this way. Here's to hoping Ep. 2 is the Arya stabby-hour (well more likely ep. 6 or 7 but who knows).
